Beta release — free, with every feature unlocked. Windows 10/11 (x64).
Who Uses It
Why STREAM
GIGABYTES OF DATA.
ZERO WAITING.
Navigate Massive Terrain Without Lag
When you open DEMs and orthophotos that are hundreds of megabytes — even gigabytes — the program never stalls. Out-of-core terrain streaming loads only the area you're looking at in full detail.
Prepare Once, Always Open Fast
On first load STREAM converts your data to its own fast format. The next time you open the same data, it appears on screen within seconds.
All Your Field Data in One Place
View DEMs, orthophotos, point clouds and CAD drawings overlaid in the same scene — together with their coordinate system.
Automatic Terrain Model from Point Clouds
When you load a LAS/LAZ file, STREAM builds a clean terrain model from ground points, a surface model from all points, or an orthophoto.
Fully Offline, Fully Yours
Your data never goes to the cloud. One online sign-in activates the licence; after that every calculation runs on your computer with no internet. Your sensitive project data never leaves the machine.
Multilingual, Two Themes
Turkish, English, Spanish, French, Chinese and Russian interface. Light/dark theme and one-click metric/imperial unit switching.
Measure Stockpiles Instantly
Compute the volume and tonnage of material piles using a reference plane and material density; get a print-ready PDF report for mining, quarry and earthworks.
Compare Two Terrains Side by Side
With multi-screen (Split View) mode, view two terrain scenarios at once with a synchronized camera. Compare before/after or design/existing at a glance.
SCREENS
REAL SCREENS, REAL SITE
Every image below is the running product on a real drone survey — no mock-ups.
INSIDE STREAM TERRAIN
One program for the whole job — from the first file to the signed report
STREAM Terrain is more than a viewer. It carries a surveying, earthworks and mining job from raw survey data to a deliverable, in one desktop application that runs offline. This is what is inside, and what each part gets you.
01
Bring your data in
Open gigabyte-scale DEMs, point clouds, orthophotos and CAD drawings in one scene — or download the ground for a site that has not been surveyed yet.
02
See, edit and measure
Pan and orbit at full resolution, correct the surface where you work, and get volumes and sections you can defend.
03
Understand the terrain
Turn elevation into decisions: where the water goes, who can see what, where the sun is — and which ground can carry a solar plant.
04
Design on the real surface
Benched slopes, roads, channels and blast patterns designed on the measured ground, with the earthwork taken from the same model.
05
Control the mine
Follow what was mined against the design, the permit boundary and the block model — and know how accurate your own elevations are.
06
Deliver
Signed PDF reports, scaled map sheets, DXF, CSV and GeoTIFF in the right coordinate system. The number on the screen is the number in the document.

Tools
THE RIGHT TOOL FOR EVERY JOB
Distance Measurement
Real-world distance between two or more points
Elevation / Height Difference
Read the elevation difference between any two points instantly

STREAM CAPTUREComing soon
From drone photos to survey data
STREAM Capture, the second product of the STREAM family, turns survey flights into point clouds, DSM/DTM, true orthomosaics and textured 3D models on your own PC — GPU-accelerated, with RTK/PPK and ground control support. Its outputs open directly in STREAM Terrain.

MAKE SENSE
OF THE TERRAIN
STREAM doesn't just show the terrain — it makes sense of it. View analysis results as a live color layer over the terrain, and save them as raster or vector whenever you want.
- Slope, aspect and viewshed in one interface
- Hydrology and drainage analyses
- Customizable contour intervals
- Profile / cross-section lines
Supported Formats
WHATEVER THE FORMAT
Elevation Model & Orthophoto
Point Cloud
CAD Project File
Digital Elevation Model
Automatic Conversion from Point Clouds
When you load a LAS/LAZ file, STREAM offers you choices: a clean terrain model from ground points only, a surface model from all points, or an orthophoto if color is present. A raw point cloud turns into real terrain you can work on.
